To all whom it may concern.'

Be it ltnown'that I, STEPHEN D. MURRAY,

a citizen of the United States, residing aty Dallas, in the county of Dallas and State of Texas, haverinvented new and useful Improvements' in Cotton-Condensers, of which the following `is a specification.

This inventionrelates to condensers for cotton gins andes eeially to the. ty e embodying doilingro s for removin tie but from the condensing cylinder and c elivering the same out of the condenser.

From considerations of cleanliness in the gmncry, also the health and comfort of the operatives, and to facilitate handling and vbaling cotton, andfor other considerations, it is important that the lint cotton should 1s sue from the condenser in a thick and com- Jact sheet free fromaccompaniment. of ily! mg-liritjan'd-diist1 ff'It is also important that the sheet orbat'of lint cotton-should be of even thicknessthrou hout as in `case it is thicker at one'ed e t an the other itfc'auses trouble in the ba ing operations andinjui to the'baling apparatus is prone to `resa t from excess ofv cotton in one side ofthe baling chamberpf:` 'A 3 Heretofore and' prior .to this`"'- invention,

condensers kwere handicapped and deficient witlrrespect 4to theaecom lishment, of the work in a' mannerto meet't ie considerations above s eciiied and otherconsiderations not specific the work of eondenscrs heretofore Irving much short of that dcgreetof etlieieucy which is desirable in the performance of the condenser for cotton gine.

ln this invent-ion the parts of the condenser are designed and organized with the object of'causing the lint cottonv to aggre-v gate at the interior of the condenser in a compact mass along and against the doliing rolls and between one of said rolls and the condensing cylinder to the end of supplying the cotton to the dofling rolls in an abundant and compact mass, which mass is still further compacted when being formed" 'into a bat between the dofllng rolls, and the cotton is reduced or compacted to a s ieet or hat of considerable densit furthermore, the -cotton aggregatedat't e interior of` thecondenser asvspecied thoroughly f. closes or'seals all avenues or openings about the dotiing rolls,

than preventing any passageot ali-ordnet into the atmosphere of the ginnery and in this way accomplishing the object of delivi ering the bat without accompaniment of tlyir'ig lint and dust. In addition to this, the ufrgregated und compacted cotton aecom- Tshes the object of preventing particles of int being carried past the dofiing rolls by the moving surface of the condensing cylinder, the compacted cotton lying along and ressing against the surface of the conenser cylinder act-ing as a wi er of the condensing ciylinderto catch anc hold all pai'- ticlcs of int brought forward by the eondenser cylinder; whereas, if the aggiegated cotton were'loose or not-compacted it would not act to catch and hold the particles of: lint, butv would allow the condenser cylin` dei' by frictional contact u on the. mass to drag some lint past the do mg rolls. Lint so dragged-pastthe doiiingv rolls is either wasted by the currentsofnir which pass out 'of thebiiildingfrom the condenser, or lodging-.in the-outer casing .of the condenser ycauseschoking ofthe condenser.` The forelgoingfundesirable features havebeen com mon'characteristicsof condcnsers as here'- tofore constructed and arranged.

`He'reto'fore ithas beenthe usual practice to o crate thedofling rolls, in the condenser "t..t e same or a.'l greater peri heral speed thanfthelperi her'al speed;of=tie condenser cylinder. ,Otiei'wisc, the condenser cylinder would' be dis osed to drag some of the lint ust thedo ng rolls. Practice seemed base' upon they theory that the dofiing rolls should remove the lint from the condenser cvlindci' as rapidly as the evlinder brou ht; tie lint forward to the dofllng rolls. )bviously, if the condenser was operated at moderate speedtlie lint would lie thicker on the 'condenser cylinder than when the eylin der was run at a higher speed, but. a layer of lint upon the condenser cylinder would obstruct: the passage or esca-pe of air through its foraminous surface, resulting in back pressure at the gins causing clicking of the cotton in the gin ribs and wasting of the lint, etc. Since it is of first importance thatl the gius he unhampered by haelt-prossure it is not practicable to improve the aetion of the condenser by reducing the speed of the condenser cylinder, andthe practice heretofore has been to o erate the condenser at a speed that woult permit the gins to operate at somewhat near their maximum eillciency and abide low efllceney in the condenser. Good work at the gine requires a good speed in the condenser cylinder so as to present to the air currents coming from the gins a large amount of fresh screen area in a given time. The speed of the condenser cylinder should be increased, but the structure of the condenser and the organization and arrangement of its arts, as will hereafter appear, iniist be suci as to result iii the performance of novel and useful functions.

In the improved apparatus embodying the features of this invention, the dotiino' rolls are run at any slow speed required to deliver a bat. of any desired thickness and the condenser is run at any greater peripheral speed which may be required to give free passage or outlet. to the air from the lint. iue or gins, while the cotton is aggregated upon the said rollers and between one of the dotiing rollers and condenser cylinder to the end that the doiiing rolls may have an abundant com act mass to act upon when forming the lint into a bat, thus enabling the doflin rolls to secure greater compactness in the at. Furthermore, the said aggregated and compacted cotton acts as before stated to catch and hold all the lint carried around bythe condenser cylinder, preventing wasting of the lint and choking of the apparatus. The eoinpacting action imparted to the aggregated cotton by frictional contact of the revolvin cylinder tends to. drive the cotton closely ownward upon the dofling rollers, while the resiliency o the fiber causes it to expand laterally, thereby filling up the soft places in the mass and so assist-in in producing a bat of even densitv throng ioiit and with'its edges full and e can-cut, in contradistinction to the thin, round and ragged edges heretofore common.

Heretofore much trouble and labor have been caused in handling and baling cotton owing to the disposition of eondensers to deliver the sheet or bat of cotton thicker at one edge than the other. Much labor and study have been expended in trying to overcome this trouble in condensers for cotton gins.

One of the objects of this invention is to construct and arrange a condenser with means to re ilate the distribution of cotton in the cont enser so same shall issue in a sheet or bat of even thickness throughout its width as will hereafter appear, and also other objects will appear.

The invention also contemplates the combinations, subcombinations, and details of construction and arrangement of the several parts which will be more fully hereinafter specified.

In the drawings: Figure 1 is an end elevation of a condenser shown applied in operative position with respect to the baling box and embodying the features of the invention. Fig. 2 is an end elevation of the condenser looking toward the extremity thereof opposite that illustrated by Fig. 1 and showing parts in cross-section. Fig. 3 is a transverse vertical section through the condenser. Fig. 4 is a longitudinal vertical section through the condenser. Fig. 5 is a. detail longitudinal vertical section of a portion of the condenser shown on a larger scale.

Similar characters of reference are cinployed to indicate corresponding parts in the several views.

The condenser coiiiprises in its organization annular end members 1 duplicate in construction and therefore advantageous not only in the preliminary preparation of the saine, but in the assemblage of the several parts of the complete condenser casing. Ihese end members are approximately circular in contour and have a metal sheathing 2 secured thereto and extending from a front rail 3 rearwardly and downwardly to a rear rail 4. A supplemental sheathing 5 is arranged at the front under portion of the casing and connected at its ower end to a rail or strip 6 and at its upper end to a smaller rail 7 located adjacent to the outlet of the condenser. The rails 4 and 6 are disposed on opposite sides of and contribute to the formation of an inlet S at the bottom of the casing, the annular members 1 being extended downwardly as at 9 to serve as end covering means or walls for the said inlet. The casing as thus described is comparatively light in its structure as well as strong and durable, and one of the important features of this condenser organization is the disposition of the inlet or feed openin@ at the bottom of the easing. Primarily both ends of the casing are open by reason of the annular construction of the end members 1, the openings 10 of the said members being of such diameter as to permit the introduction or laceinent of the condenser cylinder 11 within the casing. Over the crevice or Opening that may exist between the opposite extremities of the cylinder l1 after the latter is inserted wit iin the casing and the walls of the openin s 10, packing sti-ips of rubber or other suita le material are applied as at 10 to prevent the cotton and air escaping from tie interior of the condenser at these points.

The cylinder 11 is constructed from foraniinous sheet metal as llhavingahead 13 at one end with a dished center 14 forming a com lete closure for the end of the cylinder to which it is applied, and at the opposite end the cylinder has an annular head 15 with an outwardly projecting iiange 16 surrounding tlie opening therein. Sheet metal is referred in constructing the condenser cylinder because it can be rendered stable and self-sustaining without requiring the use of a frame or cage-like bracing means which is necessary to support a wire clot-h or gauze cylinder. Furthermore, the surface of the sheet metal cylinder is smoother than the wire cloth and is better adapted to the pecul` of air is at the opposite end of this cylinder.A

To avoid any tendency of the air currents vto flow or go too much toward the open end of the cylinder which would result in making the hat thick at that edge, a short tubular. member 17 is slipped into the open end otheacylinder. This tubular member or section is preferably made of light thin irony and lits snugly in the open end 15 of the condenser and is simply manually pushed inwardly into-the cylinder to a point to cause the escaping air currents to come more from the center of the length of the cylinder. vThe tubular member or bat regulator 17 receives air in all directions from the interior of the cylinder or permits the passage of the engaging or impinging air currents with relation to the cylinder simultaneously through all foraminous portions. It may be said that the member or bat regulator 17 is adjusted longitudinally in the cylinder or separator 11 to receive air currents moving radially from all parts and through all parts of the said cylinder or separator from the interior of the latter, and, further, the member or regulator receives air currents radially and longitudinally through the separator and is situated at the axis of the latter. This regulates the air currents perfectly and causes the said currents to distribute the cotton 'evenly or to dispose more of the cotton toward the closed end of the cylinder so as to have the bat issue of even t iclmess throughout its width. Tt is only necessary to make a single adjustment of this tubular member or section 17 after the condenser is set and put in operation, and said member or section will remain wherever it is placed. This member or section may also be said to constitute regulable means for making the bat issue from the condenser evenly or of even thickness throughout its width. The outer extremity of the section or member 17 telescopes or projects into the dust flue 18, which dust flue is intended to be extended through the wall of the ginnery to serve as a liberating or escape-means for the air and dust from the condenser cylinder.

The opening 10 formed in the casing of the condenser adjacent to the closed cylinder head and conjointly operating with the dished construction of the latter head allows driving parts cooperating with the pinion 21 and consisting of the bevel shaft 26 and the band pulley 27 to be arranged close up to this end of the condenser, whereas otherwise theywould be considerably overhun or outwardly projected.

supported y a plurality of antifrictional rollers 28 held on the .inner ends ot'4 stub `shafts 29 engaging bearings 30 at intermediate points in a plurality of vradially arends to the adjacent annular member 1 and at their inner ends bearing against and seiue 18. The antifrictional rollers 28` bear against the outer surface ofthe flange 160i the head 15 and maintain the adjacent extremity of the cylinder 1l in true ositionl Between the rails 3 and .7, :do g. rollers formed in the -front portion ofthe casing, and extending downwardly at an incline beceives the bat or sheet from the rollers and conveys it to a baling box, as shown by Fig. 1, or to any other point desired. It will be understood that the chute'may be of any length and it is not restricted in details of construction or material used in its formation. The rollers 32 and'33 have spur gears 34 and 35a respectively on one end of each, the said gears having long teeth andthe lower roller 33 is driven by the sprocket wheel 23 on its opposite end and from the said lower roller motion is imparted to the upper roller through the intermeshing spur gears 34 and 35. The bearings at the mounted in a swinging frame 37 normally held up in operative position by hooks 38 detachably engaging the frame, 1t being understood that each bearing 36 is mounted in an independent frame', and between the same and the top of the bearing is a spring 39, the springs engaging the o posite bearings acting to yieldingly holdltiie upper roller 33 in operative adjacency to the lower roller 32. By disposingl the upper roller in swinging frames as specified, the said roller may be turned down or opened outwardly and serve as densin'g chamber. The upper doing roller 33 is disposed outwardly a greater distance tion is formed between the doln ro ers and the condenser cylinder, as clear y shown by Fig. 3, the lint cotton being massed. in

this pocket prior to its exit betweenthe rollthe journal bearing 20, the bevel gear 21, the sprocket-wheels 22 and 23, together with the' sprocket chain 24 and the mechanism or ranged brackets 31 secured at their outer' cured to .the inner extremity of the dust 32 and 33 are disposed in an opening 34".

low the said rollers is a chute 35 which re-v opposite extremities of the upper roller 33 are pinion 25 onf the The lian e head 15 of the cylinder 11 iS i from the cylinder 12 than the lower doing 't roller' 32, and by this means a pocket wider-- at its upper portion than at its lower or-' connected with ,the lower inlet 8 of the 'con-- ement 'of the condenser denser.V @Thisvarran on the .upperend o Ltheiintiuesimpliiies and cheapens the condenser construction and dispenseswitli Vthe necessityA of thefiusualk Furthermore, this arran esupporting'legs. nient adapts` the condenser to .be instal ed with any ofits sides toward the gins, as it is obvious that the condenser withl the vertical portion of the lint iue may be turned to face in any dirton without requiring the least alteration in or addition to the lint iue. Below the vertical portion ofthe lint flue whichacts as asu port for the condenser-in `the manner speci ed, said flue may'be'disposed in various positions to accommodate properconnection with the gine. Hereto fore, condensers have-been arranged to-receive the lint throug'h a side opening, the liutifiue being connected with the opening at an angle, pointingyupward. The condenser so arranged was not adapted to face in any direction relative to the' gine.

Specific structural details have not'- been hereinbefore particularly referred to,as the condenser organization is .not dependent upon or confined'to vrecise'features of construetion','especially in the assemblageof the several parts,=though .it has been'foundbeneficial to use acastin inore, it will be'understood that thez'u peri terminal of the lint flue 40 will extend ully over theinlet 8, from l'front to rear and from end to end, as shown by Figs. -3 andf4. If the lint iue 40 projects upwardly throuh a flooring 47, as shown by Fig." 1, it-willj. e stiiiened and supported by'a suitable augular collar 48 secured thereto and to the iiooring, and in some instances the chute' 85 may be sup orted by a hanger' frame 49, as shown the outlet end of the said chute over the top ot the bnling box 50.'

In the operation of the condenser the condenser cylinder 11 and :i3 are set in motion, the doilln rollers being run at any slow speed retniire to bring out a hat of any desired tliie messand .the Ieylinder "rotated at y any greater r peripheral speed-that may be required to give free passageor outlet to the air from t e'lint'ue or gine. The air and lint passing upwardly l or journal bearing44. fixed inthe center o vthe disliedportion-of the head vv13 -and inwhich the inner. extremity of the l'shaft' 2li! is "secured, the ,shaft` being,y intermediately sup :ortedljgby f a-"spider "45g h1 which `thesaid Abetween the'bevel-l y Fig. 1, so as to accurately vdisposey cloning-rollers 82 and through the vertical lint fiue 40 enters the "inlet 8 into that portion of the condenser I .chamber43 .having the reatest transverse extent, and theair str1 ting the cylinder passes intothe latter and the lint continues upwardly over and iscarried around with .the cylinder toward the clotting rollers 32 and 33 and compacted-there as heretofore explained. They air'passing into the cylin- :der ,1,11 is liberated or escapes tlirough'the tubularrmember 17, and, as heretofore intimated,'inequality of air pressure within the cylinder'and any tendency toward deterioration'inl the formation of the bat or sheet thereby is rectified by the said tubular member, which is movable inwardly or outwardly, and may be properly termed a regulator. This control of the air currents and the compacting of the cotton against the doiiing rollers conjointly coperate to produce a bat or sheet of a uniform or even character and in addition the control of the air currents causes the cotton lint to be distributed equally or evenly along the condenser cylinder. This equality of distribution of the cotton lint on the condenser cylinder is facilitated in the present condenser organization and rendered more effective by having the inlet to the condenser chamber at "the bottom and causing the cotton lint to Bass upwardly through the condenser chamer and over and downwardly to the doiiing rollers,;and also inA view of the fresh, clean foraminous surface continually presented to the air currents adjacent to the inlet 8. g In testing thecondenser by means of suitablefjinspecting;,devices .it as been found thatvupon starting the gins vthe first dash of cotton into' vthe condenser follows the walls lofithecasing'around to't-he doiiing rollers and-'impinging upon the latter is deflected inwardly-to'the'adjacent portion of the condenser cylinder. In a short time the cotton 'accumulates on the top of the doiiing rollers, the aggregation of the cotton at this point continuing'as the operation proceeds. The cotton isnot drawn toward and does not adhere to the condenser cylinder l1. Nearly all-the available surface of this cylinder re- Vmains clear of cotton and is therefore open and: `veffective vfor passage of air therethrough. The o eration is similar to a vorteit` action, the" int keeping largely to the outer casingwall until it ets around to the re on where it is masse upon the doiling ro 1ers and where the pressing or impoginir air currents and the frictional contact of `the condenser cylinder impart to the mass a reliminary pacicing or condensing action, w ile the air, having practically free escapo through'a large portion ot the condenser cylinder, does not concentrate the cotton upon the said cylinder before it reaches tho doll'- ing rollers.y The etect is in a measure a centrifugal separation of the air and lint in the condensing chamber, the lint, or-

heavier body, tending toward the wall of the casing while practically all of the condenser cylinder' surface in the condensing chamber is clear and effective for the passage of air, as above noted. This operation is exceptionally advantageous in view of the prior commonly used condenser constructions and wherein the condenser` cylinders run at comparatively slow speeds and have the cotton entering at the side of the ycondenser. Under these conditions the surface of the condenser cylinder was practically covered by cotton and 'sealed against the passage of air, thus causing the air to seek outlet at and concentrate cotton upon the cylinder surface asfast asthe cotton entered the condenser chamber and in a very short time the surface of thecondenser cylinder became sealed and obstructed the free passage therethrough of the air. ln the present apparatus and as above explained, a large amount of effective condenser cylinder surface is provided for the escape of the air and in addition the cotton is directed upwardly into the condenser instead of directly against the condenser cylinder and caused to follow the circular wall of the condenser casing, and this movement of the cotton, together with the rapid rotation or increased peripheral speed of the condenser cylinder and the circular form of the outer casing results in a more effective and advantageous accumulation of the cotton on the doiiing rollers and a free escape of the air.

From the foregoing it will be observed that one of the most essential features is that the condenser cylinder may ,be run at any rapid speed necessary to always keep a comparatively large, clean screen surface available to the air currents and the slow movement of the doffing rollers to facilitate the cotton lint being carried around and packed against the dolng rollers by the driving action .of the air currents and the frictional contact or packing action of the condenser cylinder which closely amasses the cotton lint down on the doiiing rollers so as to bring out a bat of ample and even thickness. This operation also permits the condenser cylinder to be made much smaller than heretofore, while at the same time the effective opensurface of the condenser cyl-- inder is ample to allow the air to escape in view of the speed at which it rotates.
